摘要
An algorithm for the linear interpolation of multi-input functions sampled on rectangular grids is presented. A geometric approach is adopted and the mathematics is thoroughly developed. We show that the algorithm is optimum. In fact, when the number n of inputs grows to infinity its computational requirement is O(n log n), which is the same as the lower-bound on the cost of continuous linear interpolation procedures.
